Lightroom Classic: 10.2 Grain Effects Render Incorrectly In Develop Module

The Develop module no longer properly renders the Grain Effect settings in LrC 10.2, which appear much more pronounced and correct in the Library module and exported files. I tested with GPU enabled and disabled with LrC restarted and the issue persists on my Windows 10 system.

The below screenshots are with LrC 10.2 using Grain settings Amount 100, Size 50, and Roughness 100.

Have you tried comparing the Library and Develop view at 100%.

I can reproduce what you have described while at Fit view which for Nikon D850 NEFs is a zoom level of 36.7%. When I increase the zoom level (using the slider in the Library toolbar) to around 60% and greater any difference between Library and Develop is not visible.

Can also reproduce the same, grain is not rendered correctly in develop when in fit, zoomed in works fine. Win 10 20H2 x64, LrC 10.2, 4K display 150% scaling, tested with GPU ON and OFF, Smart Previews disabled. Please consider issuing a 10.2.1 hotfix for this. Otherwise with how the things have been going, next 10.x update might fix more bugs and break something else from the main/critical functionality. This way we'll at least get a proper relatively stable fallback version with the most recent new features (10.2 looks like a good candidate for this so far, except this issue). It's getting frustrating being stuck in this loop (2 bugs down, 3 new ones pop up, rollback as workaround/etc). As a suggestion to the test/dev team: consider adding automated testing for develop mode (and maybe library Loupe mode) to validate on-screen render and export results against reference images to cover all develop tools. This could benefit both devs and users a lot. Or at least consider adding a policy of thoroughly checking functionality of the develop tool across modules after something has been tweaked and fixed in it.

In Preferences > Performance, is Prefer smart previews for editing turned on or off?

I think I'm having an issue with the way noise/grain is being rendered in the editing view on my images (.jpg)

When switching between photos, the correct grain is being rendered for a split second before the full photo loads with apparent incorrect grain values. The fully loaded image seems to be rendering a de-noised version, showing little noise even when setting the grain slider to 100. Seems to have started happening after the new update.

Todd, 

Is the result the same in Camera Raw?

I'm having the same issues in Camera Raw 13.2. Grain is rendering strange.

Is this the same issue that was presented on LR Classic 10.0.0 ??  If so, this bug has been around since the release of v10 back in October..  What's going on Adobe?

Since updating to 10.2, I'm seeing the addition of what looks like grain or noise to my images when Zoom is set to anything EXCEPT "Fit" "Fill" or "100%." 

The problem goes away immediately if I hit "F" for full screen mode (even if I leave the zoom set at, for instance, 25%) or if I enter the Develop module. (This may be related to the way LR is now handling Standard previews and perhaps to the fix that was just implemented to the former color shift bug?)

A lot of my workflow relies on TIFFs of black and white film scans. These are the images where the problem is most apparent.

I'm running LR on macOS 11.2.3.

Still no word on this? No news of a possible update, or at least an acknowledgement by Adobe that this is a thing is a problem (it is).

It is the LrC v10.3 update, and STILL having this grain issue on my Mac! I really don't understand, why not fix this! AMD vga in my Macs. Catalina on macbook, Mojave on desktop. Raw files, origanal photo, not tested with smart previews. (did not tested with jpegs, but don't care jpegs)

Same issue: moving the grain slider to MAX, and still a moderate grain effect is visible only. Library, Develop, same. If I zoom in 100%, it shows the correct amount (heavy grain), but at 50% not. So Fit view, 50% view not correct grain rendering. 
This problem exist since November I guess, still no fix. And we pay for this... 
I have to use v9.4 to work with th sw.

This has been a problem for YEARS! I'm surprised so many of you think this is recent. Like everything with Adobe, I've resigned myself to leaving it alone and adding the grain in a different program. 

I've had this issue (amongst other problems) across multiple computers, FOR YEARS! Adobe does not care and will not fix it.

This is actually one of the milder creative cloud bugs.
